MOUNTING FOR SLIDING DOORS.

To all whom it may concern:

Be it known that I, ALBERT Vors'r, residing in the borough of Brooklyn,in the count-y of Kings, city and State of New York, a citizen of theUnited States, have invented new and useful Improvements in Mountingsfor Sliding Doors, of which the following is a specication.

This invention relates to the mounting of sliding doors, such as slidingdoors for show cases and the like, and relates particularly to thecarriage for carrying and separating the series of rollers upon whichthe doors are supported, and it is the object oit the invention toprovide a mounting1 for a sliding door of this character which is simpleand cheap in construction and eflicient in operation.

Further objects of the invention relate to the construction of the doorsand runways in which the rollers engage.

In the drawings accompanying and forming a part of this specification,Figure 1 is a perspective view, partly in section, of a portion of ashow case and a pair of sliding doors with my improvements appliedthereto. Fig. 2 is a sectional end view illustrating one manner ofconstructing the runway and the supporting of the doors on the rollers.Fig. 3 is a similar view illustrating a modied form of runway. Fig. 4isa view similar to Fig. 2 illustrating a still further modification ofrunway. Fig. 5 is a side elevation, partly in section, of the rollersand carriage, illustrating wipers at the ends thereof to clear therunway of any obstruction. Fig. 6 is a view similar to Fig. 5 butillustrating the carriage as consisting of sections and the manner ofreleasably connecting them together. Fig. 7 is a detail to illustratethe manner of coupling the two sections shown in Fig. 6. Fig. 8 is aside elevation of a modiiied form of carriage. Fig. 9 is a sectional endview of the carriage and rollers shown in Fig. 8. Fig. 10 is a detailend perspective of the carriage shown in Fig. 8 and illustrating meansto prevent the accidental uncoupling of the sections. Fig. 11 is adetail in side elevation of the carriage shown in Fig. 8 andillustrating a modified form of wiper connected thereto. Fig. 12 is asectional detail in perspective of a portion of the runway illustratedin Figs. 1 and 2; and Fig. 13 is a sectional detail in perspective of aportion Specification of Letters Patent.

of the binding member of the door shown in Figs. 1 and 2.

Similar characters of reference designate like parts throughout thedifferent views of the drawings.

In the drawings I have illustrated my invention in connection with themounting of sliding doors of show cases, and have shown only so much ofa show case 14 as is essential to an understanding of the invention.

In Figs. 1 and 2 the show case is provided with a pair of runwaysconsisting of juxtaposed metal strips of channel section 15, l15 inwhich engage a pair of sliding doors 16, 16, one for each runway, whichare slidable relatively to each other in the usual manner. rIhe doors insaid figures consist of glass having a metal binder 17. The doors aresupported in the runways upon rollers 18, which are carried andseparated by a carriage 19, which in Figs. 1 to 6 consists of a` metalstrip channel shaped in cross section with the open side toward thebottom of the runway, the said carriage being of less height than thediameter of the rollers and provided with cut-out portions 2O throughwhich the rollers project. At each end the carriage is provided with apivoted wiper 21 normally resting upon the bottom of the runway toremove any obstruction which may be in the path of the rollers.

If desired the carriage may be T-shaped in cross section, as shown inFigs. 8 to 11, and may be constructed by securing two pieces of angleiron together as shown in Fig. 10 with portions cut out, as at 20',through which the rollers may project, or bent up of one piece as shownin Fig. 9. In this latter construction the rollers are preferably inpairs one at each side of the carriage. The carriage is preferably madeup of sections to be connected or coupled up in any length required, andwhen constructed as shown in Figs. 1 to 6 each section is provided witha hook-shaped member 22 at one end and a laterally projecting pin 23 atthe other end to be engaged by the hook, the sections being coupledtogether as shown in Fig. 7. l

When the carriage is constructed as shown in Figs. 8 to 11 each sectionis provided at each end with a hook shaped portion 24, the hooks beingreverse to each other. In this latter construction to prevent theaccidental uncoupling of the sec- CIV tions I provide a clip 25substantially of U- shape to engage over the coupled hook portions.

In Fig. 3 the runways 15 are constructed by providing an intermediatewood section 26, in which case it would not be necessary to have themetal pieces of channel section, as in Figs. 1 and 2; in this instancethe doors are shown as consisting of wood or wooden frames for apiece ofglass. In Fig. 4 the runway is formed p by providing a channel shapedgroove in the base of the case and also in the bottom oit' the door.

Variations may be resorted to within the scope of the invention.

Having thus\described my invention, I claim:

l. In a mounting for sliding doors, the combination with a runwayand adoor slidably engaging therein, of a series of rollers engaging in therunway and upon which the door is supported, and a carriage to carrysaid rollers, said carriage comprising releasably connected sections.

2. In a mounting for sliding doors, the combination with a runway and adoor slidably engaging therein, of a series of rollers engaging in therunway and upon which the door is supported; a carriage to carry saidrollers, said carriage having no engagement with the runway or door; andwipers pivotally carried at the ends of the carriage to engage with thebottom of the runway to clean the runway of any obstruction as thelrollers move to and fro.

3. In a mounting for sliding doors, the combination with a runway and adoor slidably engaging therein, of rollers engaging in the runway andupon which the door is supported, and a carriage to carry and separatethe rollers, said carriage comprising sections having hook-shapedportions at the ends, said hook-shaped portion at one end of a sectionbeing reverse to that of its companion section whereby to releasablycouple the sections together.

4. In a mounting for sliding doors, the combination with a runway and adoor slidably engaging therein, of rollers engaging in the runway andupon which the door is supported, and a carriage to carry and separatethe rollers, said carriage comprising sections having hook-shapedportions at the ends whereby they are releasably connected together, anda clip to engage over the connection of the sections to preventaccidental separating thereof.
